Hi,
thanks for submitting the logs. It appears there is something wrong with the ‘gdm-greeter’ system user that is used for the login. The debug --collect that is in our logs procedure did not find your home directory and so we have no logs from there. You will need to gather them manually.
By default on Ubuntu 26.04 the home directory should be in /run/gdm3/home/gdm-greeter/. But since something is wrong they might be in another place. The command:
echo ~gdm-greeter
should point to them. We need the whole .nx directory that you find there. Zip that up and send as before 🙂
Can you also tell us if this is a fresh install or is it an update from another version. If it’s the latter, what version were you updating from? Also useful is any journalctl output from the last boot:
journalctl -b -1 > journal.log
